Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 104878-7 is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 5
• Number of Rows: 1
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Color: Black
• Connector Type: Header

Secondary Compatibility Parameters:

• Contact Shape: Square or equivalent geometry
• Contact Finish - Mating: Gold or Tin
• Insulation Material: Thermoplastic or equivalent polymer
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories: direct manufacturer equivalents from TE Connectivity and functionally equivalent alternatives from other manufacturers. The TE Connectivity part 5-104878-7 represents the direct successor with identical mechanical and electrical specifications. Alternative manufacturers including Samtec Inc., Mill-Max Manufacturing Corp., and Amphenol ICC provide equivalent headers with matching pitch, position count, and mounting characteristics, though with variations in contact materials, post lengths, and thermal ratings.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalent:

The TE Connectivity part 5-104878-7 is the direct successor to 104878-7 within the same AMPMODU Mod II series. This part maintains identical mechanical and electrical specifications while achieving RoHS Compliance status, addressing regulatory requirements of the original obsolete part. The primary distinction is the post finish specification: 5-104878-7 uses pure Tin finish compared to the original Tin-Lead composition. This substitution is appropriate for new designs and legacy system updates requiring regulatory compliance.

Active Product Alternatives:

For applications requiring active product status with extended procurement availability, the Samtec TSW series headers provide comprehensive substitution options. The TSW-105-07-G-S, TSW-105-08-G-S, TSW-105-23-L-S, TSW-105-23-S-S, TSW-105-23-T-S, and TSW-105-26-G-S variants maintain the critical 2.54mm pitch, 5-position, single-row configuration with square contact geometry. These parts feature Phosphor Bronze contact material and Polybutylene Terephthalate (PBT) insulation, both superior to the original thermoplastic composition. All Samtec variants carry ROHS3 Compliance and UL94 V-0 flammability ratings.

Selection among Samtec variants depends on post length requirements and contact finish specifications:

• TSW-105-07-G-S: 0.100" post length, gold finish
• TSW-105-08-G-S: 0.200" post length, gold finish
• TSW-105-08-T-S: 0.200" post length, tin finish
• TSW-105-23-L-S: 0.115" post length, gold mating/tin post
• TSW-105-23-S-S: 0.115" post length, enhanced gold thickness (30.0µin)
• TSW-105-23-T-S: 0.115" post length, tin finish
• TSW-105-26-G-S: 0.126" post length, gold finish

Alternative Manufacturer Options:

Mill-Max 800-10-005-10-001000 provides an active product alternative with circular contact geometry and brass alloy construction. This part maintains 2.54mm pitch and 5-position configuration with ROHS3 Compliance. The circular contact design represents a geometric variation from the original square contact specification.

Amphenol ICC 69190-205 (BERGSTIK® II series) offers an obsolete alternative with extended operating temperature range (-65°C to 130°C) and UL94 V-0 flammability rating. This part supports both press-fit and solder termination options and features phosphor bronze contacts. The part is classified as obsolete, limiting its suitability for new procurement.

Compliance Considerations:

The original 104878-7 is RoHS non-compliant. For applications subject to RoHS regulations, 5-104878-7 or any Samtec TSW variant provides compliant alternatives. All active product substitutes carry ROHS3 Compliance certification.

Frequently Asked Questions (FAQ)

Q: Can TSW-105-08-T-S directly replace 104878-7 in existing designs?

A: TSW-105-08-T-S maintains the critical mechanical parameters: 2.54mm pitch, 5 positions, single row, through-hole solder termination, and push-pull fastening. The primary differences are post length (0.200" versus 0.120" on the original) and contact material (Phosphor Bronze versus Copper Alloy). Designs with PCB layout constraints on post length require verification. The tin finish on both mating and post surfaces differs from the original gold mating/tin-lead post combination.

Q: What is the difference between TSW-105-23-L-S and TSW-105-23-S-S?

A: Both parts share identical mechanical specifications: 0.115" post length, 0.100" (2.54mm) pitch, 5 positions, and square contact geometry. The distinction is contact finish thickness on the mating surface. TSW-105-23-L-S provides 10.0µin (0.25µm) gold thickness, while TSW-105-23-S-S provides enhanced 30.0µin (0.76µm) gold thickness. The thicker gold finish on TSW-105-23-S-S offers improved wear resistance and contact durability in high-cycle mating applications.

Q: Is 800-10-005-10-001000 compatible with designs expecting square contacts?

A: No. The Mill-Max 800-10-005-10-001000 features circular contact geometry, whereas the original 104878-7 and most Samtec alternatives use square contacts. Circular contacts exhibit different contact force characteristics and mating behavior. Designs with specific contact geometry requirements must use square-contact alternatives.

Q: What post length should I select for my application?

A: Post length selection depends on PCB thickness and component mounting depth. The original 104878-7 specifies 0.120" (3.05mm) post length. Samtec variants offer multiple options: 0.100" (TSW-105-07-G-S), 0.115" (TSW-105-23 series), 0.126" (TSW-105-26-G-S), and 0.200" (TSW-105-08 series). Measure your PCB thickness and available mounting depth to select the appropriate post length. Longer posts accommodate thicker PCBs and provide additional solder joint material.

Q: Does the contact material change affect electrical performance?

A: The original 104878-7 uses Copper Alloy contacts, while Samtec alternatives use Phosphor Bronze. Both materials provide adequate electrical conductivity for standard signal and power applications. Phosphor Bronze offers superior mechanical properties and wear resistance. For applications with specific contact resistance requirements, both materials meet standard connector specifications.

Q: Are all substitute parts MSL 1 (Unlimited)?

A: Yes. All listed substitute parts carry Moisture Sensitivity Level 1 (Unlimited), matching the original 104878-7. This classification indicates no special moisture handling or baking procedures are required during storage or assembly.

Q: Which substitute provides the best compliance profile?

A: All active product alternatives (Samtec TSW series and Mill-Max 800-10-005-10-001000) carry ROHS3 Compliance and REACH Unaffected status. The TE Connectivity 5-104878-7 provides RoHS Compliance as the direct manufacturer successor. For new designs subject to regulatory requirements, any of these options satisfy current compliance standards.

Q: Can I use TSW-105-08-G-S in place of TSW-105-23-L-S?

A: Both parts maintain 2.54mm pitch, 5 positions, and square contact geometry. The primary difference is post length: TSW-105-08-G-S provides 0.200" post length while TSW-105-23-L-S provides 0.115" post length. Selection depends on your PCB thickness and available mounting depth. Verify that the longer post length of TSW-105-08-G-S does not create clearance issues in your assembly.

Q: What is the operating temperature range for the original 104878-7?

A: The original 104878-7 does not specify an operating temperature range in the provided data. For temperature-critical applications, Samtec TSW variants provide rated operating ranges of -55°C to 125°C (most variants) or -55°C to 105°C (tin-finish variants TSW-105-08-T-S and TSW-105-23-T-S). Amphenol ICC 69190-205 provides the widest range at -65°C to 130°C.
